A little ways forward there was an arch of sorts built between the walls of the canyon, the arch itself seemed to be made from the bones of some sort of giant snake that stretched over the air from one corner of the canyon walls to the other. The other Nagas had ran down that path and through the arch, and considering that there was no other path to take, it seems the only way left is forward. Rezar raised his head to observe the ledges that popped out of the canyon walls, basically the Nagas must have carved the entire canyon walls on both sides, expanding it and making the ledges of stealth movements.
